Accurately described in 1760 by Brisson, with its habitat correctly stated, this fine 

 species remained unrecognized until a few years ago. It seems to be confined to the 

 island of Luzon, being represented in Negros by the following species. It is the first 

 species mentioned by Vieillot (Analyse, p. 41, no. 125, 1817) under his genus Dicrurus, 

 and therefore may conveniently be regarded as the type, and Bonaparte's generic title 

 Balicassius^ must fall. -B. viridescens, Gould, was described from a Philippine example 

 now in Mr. Eyton's collection, and which I have examined. Wagler bestowed as a new 

 title that oi furcatus on Corvus balicassius, Linn., as seems to have been his habit when 

 he altered the genus. The fact that true D. balicassius is a purely Philippine bird 

 was not fully appreciated by my lamented friend the late Dr. Jerdon; for (Ibis, 1872, 

 p. 119) he alludes to the Himalayan Dicrurus as being " distinct from the Malayan 

 species to which the name of balicassius was applied." The Malayan species here 

 referred to is Molius affinis, Blyth (J. A. S. B. 1842, p. 174, "Malay peninsula"), and 

 which, after comparison, I am unable to separate from the Himalayan J), annectens. 



■which is the Tephrodornis grisola, Blyth, J. A. S. B. 1843, p. 180*, and is described op. cit. 1842, p. 799. If 

 Mr. G. E. Gray is right, and it can be shown that Hylocharis, Boie, 1825, was founded on the Hylockaris luscinia 

 01 philomela of S. MtiUer, the generic title Hyloterpe wiU have to fall. 

 ' Adopted by Fitzinger (Fam. der Viigel, p. 198).
